New Delhi: BJP on Sunday targeted Congress over CBI's handling of Ishrat Jahan encounter case, accusing it of misusing not just the investigative agency but many constitutional authorities also.

"Everyone in the country knows this truth that the Congress government has misused the CBI. Not just the CBI, but the Congress government has also tried to do the maximum misuse of other constitutional authorities in the country," said BJP president Rajnath Singh.

Ishrat Jahan, a 19-year-old college student was killed along with three others on June 15, 2004 allegedly by a team of Crime Branch officials on the outskirts of Ahmedabad, after intelligence inputs that a group of Lashkar terrorists have plotted to kill Gujarat Chief Minister Narendra Modi to avenge the 2002 communal riots in the state.

The BJP has been stung by reports claiming that the CBI has come with fresh evidence that Modi and the then Gujarat Home Minister Amit Shah had prior knowledge of the alleged fake encounter of Ishrat Jahan.

Singh also charged the Congress governments with lowering the dignity of constitutional authorities in the country. "If anyone has done the work of lowering the dignity of constitutional authorities in the country, it is the Congress government," he said.

Asked to respond to the Election Commission notice on BJP leader Gopinath Munde, the BJP chief said, "I have not heard Munde's speech. But if the Election Commission has sent a notice to Munde, he will reply."
